So I tried to get to F10 to do a system restore and F10 from the boot screen was not an option. Picked up a Toshiba Satellite 655 from a flea market for $15 yesterday, and when the computer turned on and booted to Windows, I was thinking it was too good to be true. I'm just glad to find out that Insyde is a legitimate company and the BIOS is not from a hacker trying to steal my ID and credit cards. I went online and searched for something relevant to enabling advanced settings on Insyde BIOS and there are quite some discussion around this topic, including flashing a modded firmware to BIOS and this wonderfully simple solution of The BIOS settings very much disappointed me with its about ten options with the only meaningful one being the boot order configuration. Anyhow, that only shows how remote I have been from the field. I have never seen this vendor: back when I got my last laptop, I only saw Award, AMI, and Phoenix BIOS around in the market. So I got a HP Pavilion dv6tqe recently and its BIOS is from Insyde. So when I got my new laptop, I quickly went its BIOS settings and tried to examine all its available settings and whether they are fine tuned for the best performance (CPU states/voltages, memory latency/clock, etc are crucial to achieving this goal).

Just decompressing the update utility yelds a file that is unreadable.I like to focus on details, often to a painstaking degree: I feel the constant need to adjust the balance between the details and the whole. (It's basically a dump of the text shown in the BIOS interface if it wasn't hidden)įor me it was in a file called FE3542FE-C1D3-4EF8-657C-8048606FF670_1223.ROM (yours will very likely differ)įor HP laptops you can obtain a readable fimrware image by using their BIOS update utility and having it make such plain bin files (advanced mode, third option). Now open the "DUMP" folder created by the tool (in the same place you have also the bios file), find the files that have the same ID number in their name and try to read them with the IFR extractor, one of them is the right one and will yeld a text file with a list of human-readable option names with variable offset and possible values.

Look for a module called "DXE Driver "SetupUtility", look at the ID number within brackets. Start opening all submenus to see a list of modules. Select the flashable firmware file with "Original BIOS" and then let it do its work, after it has finished click on Structure button in the lower left side of window. I used "Tool to Insert/Replace SLIC in Phoenix / Insyde / Dell / EFI BIOSes" from mydigitallife forums. You will need another tool to decompress and break up your firmware image into UEFI modules. The list of values can be dumped from the UEFI module called "SetupUtility", by using

So you can use it to read the current value if you write the offset only, or to change the value if you write the offset AND the value.Īfter you have done, turn off the PC by pressing power button until it shuts down, and then remove usb stick. The GUID should match the expected GUID, if it does not, don't continue! More importantly, you should see at the bottom that the tool is looking for the Setup variable and found it. You can now use the utility by writing setup_varĪfter you press ENTER, a license text should inform you about the risks. If everything goes well, you should see the following message>

Put this EFI application (source code: patch to GRUB2-1.96+20090709 ) on an USB-stick that is formated with FAT32 into the following directory:\EFI\BOOT\ĭisable SecureBoot and boot the USB stick in EFI mode. This is of course not my work, and I'm only adding it here because the links to the file and source patch in the blog are dead.

I add here a modified grub binary, the patch to create it, and the full blog page of the blog with the instructions. This tool and procedure was tested on a HP Envy 15 ah150sa, and it has quite a bit of interesting stuff hidden in there.
It is suitable for systems that have signed images, which will refuse to boot a modded BIOS where they are shown again.Ĭredit for the idea goes to Falseclock user in this forum (I took it from there, anyway) This system allows to modify board settings otherwise kept hidden in vendor BIOS interfaces. Tools needed to access advanced settings that are otherwise not shown in the firmware's GUI.
